With the advent of OTT, the new concept of content delivery service is growing interest in the market, the development of appropriate equipment and application program is needed. In order to provide OTT service, a system to receive UHD broadcast to collect free content is needed. In this study, we designed an OTT service providing system that operates on 4K UHD video adapter hardware capable of IPTV service. First, we analyzed the situation to provide video free contents service and implemented a system to collect free contents. To validate the research and to make practical use of it, we have developed a mobile program for free content service and distributed it through the Google App Store. It is also installed in an OTT box with the ability to provide free content on the open market and is in service in several countries including Brazil.

Barrier-free is defined as inclusive design of built environments such as building and its facilities that can be approached, entered and used by persons with disabilities. The purpose of this paper develops the content that can identify the physical barriers in the way of movement and provide information associated with barrier-free by using both Geospatial Information and Virtual Reality technology. For this, we conducted literature reviews to find the tackling barriers in terms of barrier-free access and extracted main functions to construct the content. Then, the prototype model which composed of VR engine and 3D geospatial data was implemented, and finally the utilization of the prototype was checked in accordance with barrier-free scenario. The developed prototype model of this study would be contributed to design the barrier-free of public places and access to public buildings for the mobility-disabled people.

In this paper, for maintaining the presentation quality of multimedia contents, we define the several events that can happen in showing when handle the multimedia contents. Also we classified these events in 4 types based on each characteristic. Furthermore we design the event model which can manage synchronization of presentation by control and managing the events. Also we propose an idea that maintain the quality of presentation service by interaction between each module and threads related in progress of show. Especially, in this research, we focus the active process for the user's participant and the unpredictable state variation of IMPSs(Interacitve Multimedia Presentation Systems).

The purpose of this study is to investigate the causes of pre-roll ads played before watching online video contents, and to investigate the using motives by dividing them into broadcasting contents clips and web original contents. The results show that broadcast contents clips have higher use of entertainment/habitual use and social interaction, and that the use time of web content is higher when entertainment/convenience and selective use motivation are higher. Second, perceived invasion has the greatest effect on ad avoidance in broadcasting contents clip, and positive attitude toward advertisement is a significant factor in web contents. Content factors such as content preference and engagement did not affect the avoidance of pre-roll ad.

미국 영상제작시장에서는 기획단계에서 충분한 시간, 비용투자와 여러 가지 검증방법을 통해, 아이디어를 거의 완벽하게 검증하고 있다. 최근에 사전시각화-프리비즈(previsualiztion)의 한 종류인 3D 씨네메틱스(cinematics)가 검증방법으로 활용되고 있다. 최신 컴퓨터 그래픽 기술을 이용하는 프리비즈는, 단기간에 저비용으로 제작자와 클라이언트들이 원하는 비주얼을 최종 결과물에 최대한 가깝게 구현하는 것을 목표한다. 고품질 프리비즈는 기획물에 대한 검증, 수정, 시장성타진 뿐만 아니라 프로덕션단계의 시행착오를 줄이는 가이드라인으로 쓰여, 프로덕션의 품질(quality)향상, 제작비 절감하는데 기여하고 있다. 이러한 기획에 대한 확실한 검증과정들이 미국의 영상제작산업을 세계최고 레벨로 올려놨다. 본 연구는 미국 영상제작시장에서 제작되고 있는 프리비즈의 동향과, 프리비즈 국내영상기획시장에서의 필요성, 기대효과를 연구하고자 한다.

The purpose of this study was to compare perception of importance and performance of the preceptor's role in clinical education between nursing students and preceptor nurses. Data were collected using a questionaire from 339 nursing students and 52 preceptor nurses. The perceived importance of preceptor's role was higher than the performance. Also, the perceived importance of the preceptor's role was correlated with the performance of nursing students only. It is essential to consider importance and performance of the preceptor's role in developing clinical education program for nursing students. These findings suggest that the guideline for role model and the strategies to increase performance of the preceptor's role are needed.

2002년은 다음의 '온라인 우표제'와 프리챌의 '커뮤니티 유료화' 그리고 소리바다 '불법 판결', 엔씨소프트의 '영등위 심의'등으로 정부와 업계, 업체와 업체간, 그리고 업체와 네티즌 간 이해관계에 따라 의견이 엇갈린 한 해였다. 다음 '온라인 우표제'는 업체들의 반발에도 불구하고 자리를 잡았고, 프리챌은 아직도 네티즌 끌어안기에 부심하고 있다. 2002년 마지막 화두였던 엔씨소프트의 리니지 18세 이상가 판정은 엔씨소프트의 영등위 설득 노력으로 15세 이상가 판정을 받으며 마무리되었다. 2003년은 업체와 네티즌 모드 윈-윈 할 수 있는 '수익모델'과 '새로운 서비스'가 선보이길 기대하며, 디지털콘텐츠 산업 분야에서 '온라인게임', '온라인교육', '인터넷음악', 'e-Book' 분야의 이슈를 정리해 보았다.

A synchronized multimedia presentation consists of a collection of objects, with each object having one or more rendering intervals within the presentation timeline. These intervals specify the objects' start times and end times relative to the presentation timeline. In this paper we consider the problem of streaming a multimedia presentation from a server to a client over a bandwith-limited communication network. We suppose that each of the static objects is layered-encoded. For a given maximum delay, we consider the problem of finding the optimal number of quality of the presentation. We devise efficient algorithms for determining an optimal policy for several criteria. We also consider the problem of gradual rendering of objects after their start times.

It is important to consider not only audio/video but presentation way, in video conferencing, seminar, lecture based network communication. The method to transmit image of a chalkboard used in traditional seminar, conference, lecture are one of difficulties for remote environment since it requires techniques high-resolution transmission and talking films. In this paper we implemented real-time multimedia shared board system for shared effective multimedia presentation using connection-oriented socket of TCP. In this system, decreasing cost of related system construction, improve of data reliableness and interaction, presentation delay time be able to minimize.
